Abstract

PURPOSE:To manufacture a shadow mask with etched holes in good shape and dimension accuracy and also good straightness in case the thickness of an electrode base board ranges 20-80mum. CONSTITUTION:A resist 2 is applied to both surfaces of a base material 1, and an electrode pattern is exposed only at the resist 2 on one of the surfaces. This resist 2 on the side where the electrode pattern is backed fast is developed and undergoes patterning. The resist on the counter-side with no pattern exposed is left over the whole area and is covered with a resin layer 5, which has an etching resistance, sustains the spray pressure at the time of etching, and presents reinforcement in such a degree as keeping the flatness of the base board 1. Then, unstableness of the base board 1 due to the spray pressure at the time of etching is removed, and only single side of the base board 1 is etched from the resist 2 side having undergone patterning, and thereby a shadow mask is accomplished with etched holes in good shape and dimension accuracy and good straightness.

Since the etching is performed from one side, the difference between the resist pattern width and the through-hole dimension width of the finished product (hereinafter referred to as the etching margin) becomes larger than that when etching from both sides, and the etching time is relatively long. Since it becomes longer, the unevenness of the etching surface is flattened, so that
